The c.645G>C (p.E215D) alteration is located in exon 6 (coding exon 6) of the HNF4G gene. This alteration results from a G to C substitution at nucleotide position 645, causing the glutamic acid (E) at amino acid position 215 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
